Bluetooth apparatus with ultra-low standby power consumption and method for implementing same

Abstract

The present invention provides a Bluetooth apparatus with ultra-low standby power consumption and an implementation method thereof. The Bluetooth apparatus comprises a main body and a switch apparatus. A control circuit is arranged in the main body, and the control circuit comprises a Bluetooth module, a low-level-triggered ultra-low power consumption switch module and a high-level-triggered reset switch module. The low-level-triggered ultra-low power consumption switch module is connected to a deep sleep control pin of the Bluetooth module, and the high-level-triggered reset switch module is connected to an ON/OFF end of the Bluetooth module. A switching apparatus controls the low-level-triggered ultra-low power consumption switch module and the high-level-triggered reset switch module to work. According to the present invention, when a 50 MAH battery is used on a Bluetooth headset, the standby current is 0.5 uA, and theoretical standby time can reach 2500 hours, which is amounted to 104 days. When the novel technology is used on the Bluetooth headset, standby time can increase from 4 days to 104 days, with an increase of 100 days of standby time, which greatly reduces charging frequency and improves convenience in use.
